My improvementsflrelate to cabinets for lathe accommodation and storage, temporarily or ,otherwisefof fvarious articles, "such for instance as piano music rolls; phonographic recordsy files, papers, documents, etc; in

The 'supporting frame work of my duplex cabinet consists of a bottom member 7, hereafter called for convenience the bottom plate, the mpmember f, hereinafter designated as the top plate, and the fourcorner standards oriuprights f ff f 'the spaces between said standards 7, 7, being open and free to permit of the requisite rotative m9, nipulation of the twin compartments C, C, which are mounted betweenfsaid upper and lower plates f, l

- The compartments C, C, are duplicates, inthateach consists of a back 0, and two side membersc, a", securedrigidlyto top members c ,"and bottom 1nembersc -the other or frontal portion of each Vertical elongate rectangularfboxj thuscons tituted beingopen, and: the requisite number of spacetl apart shelves 6*, icfi'being supported upon 'and'between said back and side boards 0, c ,c"",-in any "suitable manner known to theflart. Il/Vhen the compartments: are in closed relationship, as in 1 and 3, the openfsidesof the compartments are in coincidence', as shown more j particularly in Fig.

3; whe reas, whentheicabinet, considered in a unitary sense, is opened up to render the shelfspacesaccessible, these open sides of theicompartme'nts C, C, occupy a common planei at the; front of the cabinet frame, as shownmore particularly inFigf l, of the drawings. V j

*Iribrdr toattain these results in a facile manner I mount my twincompartments C, (L on rollerbearingseither countersunk in theuinder sides ofthe bottom members 0 of thecompartments O, themselves, or preferably,as s'hownin the accompanying drawingsi on roller bearings 6,6, countersunk in the upper sides of the basemember or plate hot the frame work,'-the rotative move- 'ments of said compartments being controlled bynieansoftrunnionstuds t, t, engaging with the sides of guide slots g, g, as hereinafter more fully set forth, and the adjacent front edges of the side walls 0', 0", of the compartments C, C, being pivotally connected so as to cause the two said twin compartments to move simultaneously and o in unison in opposite directions of rotation. 110

As in the case of the ball bearing supports 6, b, the arrangement of trunnion studs t, t, and guide slots 9, g, may be alternative in that the trunnion studs 25, t, might obviously be positioned on the top and bottom plates f, f, and engage with guide slots in the top and bottom end members of the compartments C, C, with like results, instead of the inverse arrangement of said parts shown in the drawings, although the latter arrangement is preferable, and consists in providing the top and bottom plates f, f, of the frame with guide channelinserts g, g, for the reception of trunnion studs 6, t, on the end members 0 of the twin compartments C, C. Thus, as will be seen by reference more particularly to Figs. 5 and 7, of the drawings, said end members 0 0 are provided with guide channels 9, g, extending medially and substantially from front torear thereof, for the reception of the Hun nion studs t, t, which inthis case are coincident with the pintles h, i of the hinges h, k, by means of which the aforesaid adjacent front edges of theside walls 0', 0", are pivotally connected, this feature of construction being shown in detail particularly in Fig. 10. The function of these hinge trunnion studs t, t, is to maintain the juxtaposition frame, and are positioned medially as related to the back and front thereof,

as shown in Figs. 5. and '7. The function of the pivotal trunnions t, is to insure the axial rotation of the twin compartments C, C, and the transverse guide channels g, g allow them to do this while compensating for the lateral side thrust, in opposite directions, of the compartments incidental to their pivotal connection with each other as aforesaid.

It is of course toxbe understood in this connection that thesets ofguide grooves g, g, and the trunnion studs t, t, are duplicated at top and bottom of the cabinet for each container 0.

N In Fig. 11, of the'drawings, I indicate diagrammatically the evolutions involved in the opening or closing of the twin compartments C, G, the solid lines m-a:, representing either the open or closed position thereof; the lines yg the intermediate positions of the compartments; and the lines the prescribed arcs of circles traversed. by the free corners of the compartments during rotative transition in either direction. It is to be noted in this connection that the lines .e.z, of the free corner movement of the compartments C, G, are entirely within and clear the corner posts or standards f, F, of the frame work; and that the twin compartments are rotative to the extent of a quarter turn in either direction, their pivotal connection preventing more than that extent of movement, and maintaining their alignment and co-relation.

By means of my twin compartments thus arranged, combined and connected, I obviate the necessity for the use of doors, while attaining a closable cabinet with a maximum of capacity in a minimum of space. Furthermore my duplex cabinet is simple both in construction and operation, and may be manipulated with facility.

What I claim as my invention and desire to secure by Letters Patent is,

l. A doorless closable cabinet of the character designated, comprising a supporting frame, pivotally connected rotative twin compartments mounted therein, each with an open side and said open sides coincident when the compartments are in closed relationship, and guide channels and engaging trunnion studs arranged to control the rotative movements of said twin compartments.

2; A doorless closable cabinet of the character designated, comprising a supporting frame, rotative twin compartments mounted therein and pivotally connected to each other at adjacent edges only, each with an open side and said open sides coincident when the compartments are in closed relationship, and guide channels and engaging trunnion studs arranged to control the rotative movements of said twin compartments.

3. A doorless closable cabinet of the character designated, comprising a supporting frame having guide-channelled top and bottom members, and twin compartments mounted therebetween, said twin compartments being pivotally connected at adjacent edges and being fulcrum connected with said guide channels in the top and bottom members of the frame.
